ABSTRAK

Dalam proses pemotongan mesin, ketepatan pemotongan, masa pemotongan dan kecacatan sifar adalah faktor yang sangat penting kerana produk yang berkualiti tinggi mendapat permintaan tinggi di dalam industri. Terdapat beberapa faktor yang menyebabkan masalah berlaku kerosakkan antaranya adalah getaran yang berlaku semasa permulaan pemotongan dan pergerakan muncung semasa memotong. Masalah lain adalah disebabkan oleh keupayaan mesin. Jubin adalah bahan rapuh dan mudah pecah terutamanya pada kawasan pemotongan yang rumit. Terdapat tiga objektif yang ingin dicapai dalam kertas kerja ini. Pertama adalah untuk menentukan Kadar Pembuangan Bahan jenis jubin seramik menggunakan ‘Abrasive water jet’ (AWJ) dan kedua untuk mengkaji potensi berlaku kecacatan pada reka bentuk sudut yang berbeza dan yang terakhir adalah untuk mencari parameter pemotongan yang sesuai untuk memotong bahan jubin seramik. Oleh itu terdapat tiga ujian yang akan dijalankan itu adalah ujian kadar pembuangan bahan, ujian reka bentuk pada berlainan sudut dan kualiti permukaan pemotongan. Selepas ujian dijalankan kertas kerja ini boleh menyimpulkan bahawa keseluruhan objektif telah dicapai. Objektif pertama dicapai selepas mendapatkan ketebalan tekanan yang sesuai, iaitu tekanan ketebalan 6mm (mesin). Objektif kedua tercapai apabila dapat menentukan parameter yang boleh memotong jubin tepat di samping mempunyai kos yang rendah. Objektif ketiga dapat dicapai selepas mendapatkan ketebalan tekanan yang sesuai dan mendapat permukaan pemotongan yang baik. Selepas melakukan pemerhatian tiga ujian ini, salah satu parameter yang terbaik telah dipilih iaitu ketebalan tekanan 6mm (mesin).

ABSTRACT

In a machine cutting process, accuracy cutting, time cutting and zero defect is very important factor because the demand is high to have a high quality product. There are several factors that cause these problem most of the root cause is vibration during start cutting done and the movement of the nozzle during cutting. The other problems are due to design limitations. Tile is brittle material and easily to break especially in the intricate cuts area. There are three objective needs to be achieve in this paper. First is to determine the Material Removal Rate (MRR) of ceramic tile using AWJ and second to study the potential defects at different angle design and the last is to recommended the suitable AWJ cutting parameters to cut ceramic tile materials. Therefore there are three testing to be carried out it is material removal rate experiment, design angle experiment and surface quality experiment. After get the result it can be conclude that whole objective have been achieved. The first objective was achieved after get the suitable pressure thickness, it is a 6mm pressure thickness (machine). The second objective are achieved when able to determine which parameters can cut tile accurately in addition have a low cost. The third objective get achieved after get the suitable pressure thickness versus surface roughness. After doing the observation of three result, one of the best parameter was chosen that is pressure thickness of 6mm in machine.

CHAPTER 1 INTRODUCTION

1.1 Background

Nowadays, many process use advance machining such as chemical process, electrochemical process, thermal process and hybrid electrochemical process. The Abrasive Water Jet Machine (AWJM) is one of the advance machining process. AWJM is suitable to cut harder material such as glass, ceramics, concrete, and tough composites can be cut by adding abrasives to the water jet during abrasive water jet machining (Hassan, 2005).

Abrasive water jet was selected because it does not have contact with tools, no heat zone and low machining force when cutting is apply. While temperature at the impact zone can be very high, total temperature is low. The presence of a high speed waterjet acts very effective convective coolant as well. Hence, AWJ is most suitable for machining heat-sensitive and hard to machine materials. The AWJM is able to cut any material and can be used without using a fixtures modification or special fixtures or tooling. In AWJM the same cutting tool can be used for drilling, milling, turning, and contouring of virtually any geometry; possibility, replacing an entire work shop of machine tools. So it is very suitable for use in this experiment, because in this experiment, there are many types of cutting used for the purpose of obtaining state MRR rate and there are several types of tiles are used to cut and to make analysis. AWJM is simply composed of water and some naturally occurring minerals. It does not require synthetic oils or other chemicals for lubrication and cooling. All components of an AWJ are environmentally friendly and recyclable. (Mark et al. 2011).

(20)

Abrasive water jet (AWJ) is a new technique for cutting difficult to machine materials and make cutting without reducing the properties of material (Pang & Wang, 2009). The AWJ typically used in industry to cut ceramics, or hard material (El-Hofy, 2005). AWJ uses an abrasive to do the cutting path on the work piece using compress water and released through a nozzle. Because of the high velocity, the cutting could be done quickly. This machine cuts almost all types of materials (conductive and nonconductive). Where the traditional machine unable to perform effectively especially on brittle and ductile materials. Non conversional machining process have been introduced to do cutting and improve the productivity compared to traditional machine (Palleda, 2007).

In this study, many types of tile are selected for testing to obtain the material removal rate (MRR). This material was chosen because it easy to cutting, obtain MRR and flow rate. This study also aim to determine the cause of the cracks and other possible defects. So the easiest way to examine the damage and cracking is by using a digital camera pictures and make comparison analysis.

1.2 Problem statement

There are several factors that cause these defects to occur, which are caused by vibration from beginning of the cutting and the movement of the nozzle during cutting (Orbanic, 2008). Tile is a brittle material and easily to brake during cutting. Abrasive water jet cutting machine usually causes cracks in the intricate cuts area. Besides that, a lot of material waste after the cutting is done. Therefore the main objective of this study are as following.

(21)

1.3 Objective

1) To determine the Material Removal Rate (MRR) of ceramic tile using AWJ.

2) To study the potential defects at different angle design.

3) To recommended the suitable AWJ cutting parameters to cut ceramic tile materials.

1.4 Scope of project

This study focuses on different materials of ceramic tiles namely mosaic tile, stone tile, ceramic tile, vitrified tile. Used the abrasive water jet model Flow Water jet MACH2. Abrasives used in this study of size 13/40 with 80 mesh. Data is analyze material using Excel and T-Test (Minitab). Digital camera is used to capture the defect images of tiles. The MRR of each sample is obtained by weighing the material before and after experiment is use the digital scales.

CHAPTER 2 LITERATURE REVIEW

From the early stage of the project, various literatures studies have been done. Research journal, reference book, printed or on line conference article were the main sources of information. This chapter review topics such as Abrasive water jet machine (AWJ), impact AWJ machine, and methods to perform correlations analysis.

2.1 Type of machine

Machining processes produce finish product with a high degree of accuracy and surface quality. The need for higher machining productivity, product accuracy, and surface quality will led to the combination of two or more machining actions. (Helmi et al. 2008)

(23)

2.1.1 Conventional machine

During recent years, engineering materials have been greatly developed. The conventional machine such as lathe machine, milling machine and drilling machine also is impossible to machine hard material to certain shape. This is because the conventional method is not suitable to machine some of the material economically and it is harder than the materials that available for cutting tools. By using conventional machine, the cutting speed and MRR is not consistence. It is possible to find tools material that are hard to cut such as hardened steels, austenitic steels, carbides, ceramics and fiber-reinforced composite material. (Helmi et al. 2008)

2.1.2 Non-conventional machine.

Nowadays, non-conventional machining process are generally classified into different type of energy utilized in material removal such as mechanical processes. In mechanical process, material removal is depends on mechanical abrasion or shearing. It will integrating two or more non-conventional process to improve the performance of the removal rate in the hybrid process (HP). The example of the mechanical process is electrochemical grinding (ECG), electrochemical honing (ECH), electrochemical ultrasonic machining (ECUSM) and abrasive water jet machining (AWJM) (Hassan, 2005).

(24)

2.2 Abrasive water jet machine

Water jet machining (AWJM) is suitable for cutting plastics, rubber insulation, automotive carpeting and headlines, and most textiles. Other than that, AWJ machine suitable for cutting hard material such as glass, ceramics, concrete and tough composites. AWJM was first developed in 1974 to clean metal prior to surface treatment of the metal. Generally, AWJM cuts 10 times faster than conventional machining (Hassan, 2005).
